| 摘 要： | 为研发适用于我国农村的分散式污水处理装置，采用厌氧+跌水曝气+人工湿地组合工艺对农村生活污水进行处理，考察组合工艺对COD、TN、TP、NH4+-N、SS 5个常规指标的去除效果及对各指标的沿程去除情况。结果表明，组合工艺对COD、TN、TP、NH4+-N和SS的平均去除率分别为74.5%、57.2%、59.5%、59.00%和91.6%。人工湿地对COD、TN、TP和NH4+-N的去除率最大，分别为31.0%、36.7%、43.9%和30.0%；而厌氧反应池对SS去除贡献率最大，为40.3%。该组合工艺处理农村生活污水具有良好的处理效果，且装置运行能耗低，利于推广应用。

| Abstract: | To develop the decentralized sewage treatment devices suitable for rural areas in China, a combined process of anaerobic tank,drop-aeration and constructed wetland was developed to treat the rural domestic sewage. The removal rates of five conventional indexes (COD, TN, TP, NH4+-N and SS) and their changes along the process were studied. The results showed that their removal rates were 74.5%, 57.2%, 59.5%, 59.00% and 91.6%, respectively. The constructed wetland had the highest removal rates of COD, TN, TP and NH4+-N, which were 31.0%, 36.7%, 43.9% and 30.0%, respectively, while anaerobic tank had the largest SS removal rate of 40.3%. The combined process has a good performance on the rural domestic sewage treatment with low energy consumption, which is conducive to its popularization and application. |
